No need to pack bearings or deal with a greasy cleanup. This CE Smith idler hub comes pre-greased and ready to go, so you can slide it onto your spindle and be back on the road in minutes. It’s built for 3,500-lb axles with #84 spindles and includes everything you need—inner bearing (L68149), outer bearing (L44649), both races, grease seal, grease cap, lug nuts, and cotter pin. Each hub carries 1,750 lbs, giving you a strong and dependable setup that’s quick to install.
You can count on this hub to stand up to the elements. The sturdy iron body handles everyday hauling with confidence, while zinc-plated lug nuts, cotter pin, and grease cap help hold back rust and corrosion—especially handy around water or in humid conditions. It’s a solid piece of gear that keeps things turning smooth season after season.
Finding the right fit doesn’t have to be a guessing game. This hub uses the common #L68149 inner bearing ("1.378" inner diameter) and #L44649 outer bearing ("1.063" inner diameter) found on most 3,500-lb axles. The included grease seal (#58846) has a "1.719" inner diameter and "2.565" outer diameter, giving a snug seal that keeps grease where it belongs. Match your spindle dimensions to these numbers and you’re set for an easy swap.
If you’re running an idler axle setup without brakes, this hub keeps things simple and reliable. It fits wheels from "14-1/2"" to "16"" with a "6 on 5-1/2"" bolt pattern and a "7"" flange diameter. Whether you’re replacing old hardware or building out a fresh trailer setup, it’s designed for straightforward use and long service life without extra complexity.
1. Count the lug holes
Look at the wheel hub or the back of the wheel and count how many lug holes there are(also called bolt holes).
Common configurations include: 4-lug, 5-lug, 6-lug and 8 lug
2a. For even lug counts (4-lug, 6-lug, 8-lug)
Measure from the center of one lug hole directly across to the center of the hole opposite it.
Common configurations: 4 on 4", 6 on 5.5", 8 on 6.5"
2b. For odd lug counts (5-lug)
Measure from the center of one lug hole to the outer edge of the hole directly across (not center-to-center since there's no directly opposite hole).
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"
